BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevilla plant, botanically known as Mandevilla sanderi andhereinafter referred to by the name ‘Lannorthdakota’.

The new Mandevilla plant is a product of a planned breeding programconducted by the Inventor in Malause, France. The objective of thebreeding program is to create new vigorous and freely branchingMandevilla plants with numerous unique and attractive flowers.

The new Mandevilla plant originated from a cross-pollination conductedby the Inventor in Malause, France during the spring of 2016 of aproprietary selection of Mandevilla sanderi identified as code number siu231-0, not patented, as the female, or seed, parent with Mandevillasanderi ‘Lanmalause’, not patented, as the male, or pollen, parent. Thenew Mandevilla plant was discovered and selected by the Inventor as asingle flowering plant from within the progeny of the statedcross-pollination in a controlled greenhouse environment in Malause,France during the spring/summer of 2018.

Asexual reproduction of the new Mandevilla plant by cuttings in acontrolled greenhouse environment in Malause, France since September,2019 has shown that the unique features of this new Mandevilla plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Lannorthdakota’. These characteristicsin combination distinguish ‘Lannorthdakota’ as a new and distinctMandevilla plant:

-   -   1. Broadly vining plant habit.    -   2. Moderately vigorous to vigorous growth habit.    -   3. Freely branching habit.    -   4. Glossy dark green-colored leaves.    -   5. Early and freely flowering habit.    -   6. Flowers with rounded red purple-colored petals and broad dark        yellow-colored throats.

Plants of the new Mandevilla can be compared to plants of the femaleparent selection. Plants of the new Mandevilla differ primarily fromplants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vining than and not as        compact and upright as plants of the female parent selection.    -   2. Flowers of plants of the new Mandevilla have rounded red        purple-colored petals and broad dark yellow-colored throats        whereas flowers of plants of the female parent selection have        pointed white-colored petals with narrow orange-colored throats.

Plants of the new Mandevilla can be compared to plants of the maleparent, ‘Lanmalause’. Plants of the new Mandevilla differ primarily fromplants of ‘Lanmalause’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vining than and not as        compact as plants of ‘Lanmalause’.    -   2. Plants of the new Mandevilla are more freely branching than        plants of ‘Lanmalause’.    -   3. Flower petals of plants of the new Mandevilla are red purple        in color whereas flower petals of plants of ‘Lanmalause’ are red        orange in color.    -   4. Flowers of plants of the new Mandevilla resist fading under        high light exposure whereas flowers of ‘Lanmalause’ fade under        high light exposure.

Plants of the new Mandevilla can also be compared to plants ofMandevilla sanderi ‘Rosea Fonce’, not patented. In side-by-sidecomparisons, plants of the new Mandevilla differ primarily from plants‘Rosea Fonce’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more freely branching than        plants of ‘Rosea Fonce’.    -   2. Plants of the new Mandevilla flower much earlier than plants        of ‘Rosea Fonce’.    -   3. Plants of the new Mandevilla have larger flowers than plants        of ‘Rosea Fonce’.

Plants of the new Mandevilla can also be compared to plants ofMandevilla sanderi ‘Sunparapibra’, disclosed in U.S. Plant Pat. No.19,649. In side-by-side comparisons, plants of the new Mandevilla differprimarily from plants ‘Sunparapibra’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vining and vigorous        than plants of ‘Sunparapibra’.    -   2. Flowers of plants of the new Mandevilla have red        purple-colored petals and broad dark yellow-colored throats        whereas flowers of plants of ‘Sunparapibra’ have light        pink-colored petals with narrow orange-colored throats.    -   3. Plants of the new Mandevilla are more resistant to fungal        pathogens than plants of ‘Sunparapibra’.
